sustaining lubricant. Still more specifically the invention relates toradial bearings of the above type made in the form of separate unitshaving an annular inner member adapted to. be mounted on a shaft or thelike.

' The principal object of the invention is to provide means forretaining the bearing blocks in their proper position with respect tothe bearing members and for preventing are mounted in the position inwhich they are intended to operate. Further objects and the manner inwhich theinvention may be carried intoeffect are more fully disclosed inthe following description of the forms of apparatus illustrated in theaccompanying drawing forming a part of this specification.

In the drawing; Fig.1 is a longitudinal central section of a bearingembodying the invention;

Fig. 2 is an elevation of the bearing shown inFig. 1, looking from theright; and

a Fig. 3 is a view similar toFig. 1 another form of the invention.

Referring now to the drawing, 1 designates w an inner bearing memberwhich in the present'instance is in the form of a ringadapted to bemounted on the shaft 2. Radially spaced from ring 1 is the outer bearingmember or race 3 adapted to be fixed in a casing or the like. Aplurality of bearing blocks 4 are disposed radially between ring landrace 3, the inner face of each of theblocks being provided with aprojection 5 forming bearing surfaces an and o. Ring ,1 is provided witha plurality of notches 6, the shoulders thereof forming bearing surfaces0 and d.

showing the cooperating bearing surfaces are'peripherally to one sideofthe centers of the blocks.

with respect tothe race 3 due to thefact'that Upon rotation of shaftQZand ring 1 in the opposite direction theblocks shiftperiph erally sothat surfaces b' andd engage to cause tilting of the blocks intheopposite direction;

Ring 1 is further provided with: a series of segmental peripherallydisposed flanges 7- extendmg into peripheral groovesS in the blocksto'prevent axialdisplacement of the blocks with respect to the ring andeach flange 7 has a radially extending boss 9 there-;

on. The bosses 9' act'to limit peripheral move- V ment of the blocks,but are so; spaced. as to disassembly of the bearingunits before theypermit the above described peripherallshiftdriving member of thebearing.

taining the lubricant in the vbearing For a.

By reference toFig. 1 it will be seen that with the members 1 and 3 in acommon plane,

as shown inthe figure-the blocks are held radially and axially inposition between these members. Because, however, ofv the spheriez;

cally curved surfaces 10 and 11 the position of the members can beshifted so that one or more of the blocks 4: move out of engagement withthe race 3, in which event the block or 5 blocks will fall out ofposition. The same also holds true in the case of bearings havingcylindrically curved surfaces 10 and 11, if the ring 1 is moved axiallya sufficient distance with respect to race 3; 10 In accordance with thepresent invention, this possibility of disassembly of the bearing unit,due to relative displacement of parts,v

is prevented by providing means for limiting the displacement of ringland its associated ,blocks twith respect to the race 3. 1

-In the form'shown in Figs. 1 and 2 this 'f means comprises a pluralityof wire clips -12 in theform'. of staples the legs of which pass throughsuitable axial holes in the r'aceB, both ends of the staples being bentradially inwardly as at 13, so as to limit'axial displacement of theblocks 4 with respect to the rac'eB. WVith movement of blocks lthusrestricted the entire bearing is held together 7 as a unit, since axialdisplacementof the drivv ng ring is prevented by the flanges 7 in.grooves 8, Afterv the bearing unit has been installed, with the race 3secured in acasing .or the like the 'clips 12 may-be :removed or --the ymay be permitted to remain in place. If the clips 12 are intended to beleft in position during operation of the'bearing, the-axial rdistancebetween .the inturnedends 13 should tting-the bearing to .align itself.

I While preferred forms of the invention have :beenill-ustrated by wayof example, the invention may obviously be carried out by means of otherforms of apparatus-which uwill occur to those skilled'in the art. Theinvention :isit'herefore to be understood-as not l mited to the formsshown, but-is to ibecons dered as. including all such changes andvariations as may fall within the scope of the appended'claims.
